Planting Calendar for Geum

Frost tolerance for geum:	Tolerant of a very small amount of frost.
When to plant:	Up to 3 weeks before last frost.

Geum do well in very little cold which means that you can plant them just a tiny bit earlier in the year than plants that are more sensitive to the cold.

The last month that you can plant geum and expect a good harvest is probably September. You probably don't want to wait any later than that or else your geum may not have a chance to grow to maturity. Starting your geum indoors is a great way to get them started a few weeks earlier.
